"What was the implication? If Dave shelled out the cash he'd get info?"
the implication COULD HAVE BEEN that he'd have gotten his daughter!
That's kind of what I'm wondering - I still believe she was alive - longer than maybe we know.
I also still wonder about the phrasing of Paul's statement "not likely to find her" or whatever and the thought that she was shipped off the island.
I could be wrong - but I really think they'd have found her remains if they took care of it in a haphazzard manner. If Depak was the one to kill her and "burn" her then there would be remains to be found.
